L'apport du réaffûtage à la variabilité morphométrique des pointes de projectile aurignaciennes en bois de cervidé

Doyon, Luc 04 1900 (has links)
Ce projet combine l’archéologie expérimentale, l’analyse morphométrique et la comparaison des résultats à l’assemblage archéologique de l’Abri Cellier (Dordogne, France) (N = 12) dans le but de quantifier l’apport du réaffûtage à la variabilité des formes et des dimensions des pointes de projectile aurignaciennes en bois de cervidé. La relecture morphofonctionnelle de la série expérimentale de Knecht (N = 79) couplée à une reproduction expérimentale récente (N = 9) démontre que la nature des dommages infligés au fût des pointes dépend (1) de la force du tir, (2) de la nature de la cible impactée et, (3) des propriétés biomécaniques du matériau employé. Pour sa part, le réaffûtage dépend (1) de l’expérience du réaffûteur et, (2) de la séquence technique employée. Ce comportement est standardisé et demeure indépendant du type de pointe de même que du type de dommage du fût. Les changements morphométriques associés à ce comportement se résument (1) à un déplacement progressif de l’épaule de la base vers le fût de la pointe, (2) à une tendance à l’accroissement de l’angle du fût et, (3) à une localisation des traces de réaffûtage sur le tiers distal de la partie distale de la pointe. Puisque l’utilisation et le réaffûtage sont deux processus impossible à départager sur les artefacts, nous proposons l’adoption d’une mesure, le ratio proximo-distal (RP/D) afin de traduire l’intensité de ces processus convergents et faciliter la comparaison entre les assemblages archéologiques. / This project combines experimental archaeology and morphometric analysis with a comparison with the archaeological assemblage from Abri Cellier (Dordogne, France) (N = 12) to quantify the contribution of resharpening to morphometric variability of Aurignacian projectile points made of antler. A morpho-functional re-analysis was performed on the experimental series produced by Knecht (N = 79), and combined with a recent experiment (N = 9) which showed that tip damage depends on (1) the projectile velocity, (2) the nature of the impacted target and, (3) the raw material’s biomechanical properties. On the other hand, resharpening depends on (1) the curator’s experience and, (2) the employed technical sequence. Also, resharpening is considered a standardized behaviour that remains independent of the point or tip damage type. Morphometric changes incurred by this behaviour can be summarized by (1) a gradual shift of the point’s shoulder from the base to the tip of the point, (2) a tendency of the tip to become more obtuse, and (3) a concentration of the curation stigmata at the distal third of the tip. Since use and resharpening are two processes that can’t be distinguished metrically on archaeological specimens, we propose a new metric the Proximo-Distal Ratio (RP/D), which translates the intensity of these two converging processes and allows inter-assemblage comparison.

The Paleoamerican occupation of Darke County, Ohio, and environs

Holzapfel, Elaine Kester January 2001 (has links)
This thesis develops and executes a method of comprehensively discovering accessible Paleoamerican archaeological materials from a restricted geographic area, analyzing the data collected, and comparing them within a larger sphere of interaction. The restricted area was Darke County, in west-central Ohio. The study area was familiar to the writer both in field experience and knowledge of collections held by local residents. A total of 115 diagnostic points and additional tools were located, examined, photographed, and measured.On the basis of point typology three stages of Paleoamerican occupation were identified, Early (11, 500 to 10, 500 B. P.), Middle (11,000 to 10, 500 B. P.), and Late (10,500 to 10,000 B. P.). The Early Paleoamerican stage was marked by Clovis fluted and Unfluted fluted points, the Middle by the Cumberland point, and the Late by Agate Basin, Transitional, Plano Lanceolate, and Hi-Lo points. The sources of raw materials were identified and changes of habitat through time were described.The abundant data recovered and analyzed by the approach used in this study from just one Ohio county indicates that extensive data is available but has yet to be recorded and analyzed for Paleoamerican occupation throughout Midwestern United States. / Department of Anthropology

The Manning cache : an examination of the McWhinney heavy stemmed point

Gullion, Chris S. January 2008 (has links)
This thesis will explore the significance of a cache of Late Archaic lithics found in Randolph County, Indiana by Bobby Manning. These points, thought to mostly be of the McWhinney Heavy Stemmed type are unique in that very few caches of these points have found been in such good condition in unmixed contexts. The McWhinney Heavy Stemmed point, as currently defined, is not well represented in the archaeological record. Point typology is important to archaeology because point types indicate the age and cultural affiliation of most surface sites. Point typologies, then, require accurate description of good samples from unmixed contexts. By presenting background data concerning the McWhinney Heavy Stemmed point and known morphological correlates this thesis aims to provide a better description of the point type. Also this data, coupled with the data from the Manning cache is used to produce results that determine the significance of the cache and determine if this isolated cache reflects a new variant in the McWhinney type or, if justified, a new type altogether. / Department of Anthropology

Mountains as crossroads : temporal and spatial patterns of high elevation activity in the Greater Yellowstone ecosystem, USA

Reckin, Rachel Jean January 2018 (has links)
In the archaeological literature, mountains are often portrayed as the boundaries between inhabited spaces. Yet occupying high elevations may have been an adaptive choice for ancient peoples, as rapidly changing elevations also offer variation in climate and resources over a relatively small area. So what happens, instead, if we put mountain landscapes at the center of our analyses of prehistoric seasonal rounds and ecological adaptation? This Ph.D. argues that, in order to understand any landscape that includes mountains, from the Alps to the Andes, one must include the ecology and archaeology of the highest elevations. Specifically, I base my findings on new fieldwork and lithic collections from the Absaroka and Beartooth Mountains in the Greater Yellowstone Ecosystem (GYE) of the Rocky Mountains, which was a vital crossroads of prehistoric cultures for more than 11,000 years. I include five interlocking analyses. First, I consider the impacts of anthropogenic climate change on high elevation cultural resources, focusing on the diminishing resiliency of ancient high elevation ice patches and the loss of the organic artifacts and paleobiological materials they contain. Second, I create a dichotomous key for chronologically typing projectile points, suggesting a methodological improvement for typological dating in the GYE and for surface archaeology more broadly. Third, I use obsidian source data to consider whether mountain people were a single, unified group or were represented by a variety of peoples with different zones of land tenure. Fourth, I consider high elevation occupation in both mountain ranges as part of the seasonal round, using indices of diversity in tool types and raw material to study how the duration of those occupations changed through time. And, finally, I test the common contention that ancient people primarily used mountains as refugia from extreme climatic pressure at lower elevations. Ultimately, I find that, in both mountain ranges, increased high elevation activity is most highly correlated with increased population, not with hot, dry climatic conditions. In other words, the mountains were more than simply refugia for plains or basin people to occupy when pressured by climatic hardship. In addition, between the Absarokas and the Beartooths the evidence suggests two different patterns of occupation, not a monolithic pan-mountain adaptation. These results demonstrate the potential contributions of surface archaeology to our understanding of prehistory, and have important implications for the way we think about mountain landscapes as peopled spaces in relation to adjacent lower-elevation areas.
